In celebration of the 50th anniversary of Earth Day, San Diego Zoo Global is launching a Virtual Earth Day Celebration, where online visitors can participate in fun activities and gain access to educational resources—all while learning ways to better co-exist with nature.

Amahle, the San Diego Zoo’s youngest river hippo, is growing rapidly—and she’s already showing her curious side, exploring her habitat and seeking out new areas to investigate when her mom, Funani, isn’t right by her side.
